Answer:

23

Step-by-step explanation:

you always do whatever is in the brackets first,

31 - 9 = 22

then the equation would be,

45 - 22

so the answer is 23

hope this helped xx

Pemdas states that the equation in parenthesis comes first. With that in mind, let’s solve:

31 - 9 = 22

Now that we have solved, we can properly subtract 22 from our other number, 45:

45 - 22 = 23

45 - (31 - 9) = 23.
